Estrogen Regulates the Expression of Retinoic Acid Synthesis Enzymes and Binding Proteins in Mouse Skin

The conversation discusses the mechanism of action of alfatradiol (17 alpha estradiol) in treating hair loss. It explores theories that it either inhibits 5 alpha reductase to prevent T->DHT conversion or aromatizes scalp T into 17-alpha-estradiol to save hair.

17-alpha-estradiol may work for hair loss by inhibiting 5-alpha reductase, similar to finasteride. It might lower testosterone in the scalp, reducing DHT conversion.

IGFBP‐rP1 shows potential for treating androgenic alopecia by influencing hair cycle transitions. Increasing IGF-1 levels may have similar effects to Minoxidil and 5-AR inhibitors in reducing hair loss.

The conversation discusses a hair loss treatment regimen including finasteride, minoxidil, micro needling, and oil blends. It questions the addition of retinol, with feedback suggesting tretinoin is more effective, while retinol may cause hair loss.

The conversation discusses using a multimodal approach to treat androgenic alopecia, including substances like gamma-linolenic acid, DHA, sulforaphane, melatonin, cetirizine, astaxanthin, fisetin, apigenin, curcumin, limonene, genistein, and berberine. Users also mention using ketoconazole, minoxidil, and low-level laser therapy (LLLT) as part of their hair loss treatment regimens.

Topical estradiol may help with hair loss but can have systemic effects, like reduced testosterone production. Using estrogen blockers can have negative side effects, such as joint pain and reduced sex drive.
